[0027] The screening mechanism 2 comprises a mounting frame 22, the mounting frame 22 is hingedly connected to the left side of the top of the support frame 1, two sides of the mounting frame 22 are fixedly connected with rollers 26, the rollers 26 are fixedly connected with a rotating rod 27 in the middle, the rotating rod 27 is fixedly connected with a chain wheel set 25 on one side close to the left side, the chain wheel set 25 is fixedly connected with a first motor 24 on the other side, the bottom of the first motor 24 is fixedly connected with the bottom of the mounting frame 22, the top of the rollers 26 is rollingly connected with a rotating drum frame 21, the rotating drum frame 21 is fixedly connected with a screening drum 28, and the bottom of the left side of the mounting frame 22 is fixedly connected with a discharge chute 23.

[0028] The screening mechanism 2 and the feeding mechanism 3 feed the aged waste into the screening drum on the right. Then, the first motor 24 and the chain wheel group 25 drive the rotating rod 27 to rotate. At this time, the roller 26 will rotate along with it, driving the entire rotating drum frame 21 to rotate. At this time, the aged waste in the screening drum 28 with three different screening holes will be screened by centrifugal force, and the waste of different sizes will fall through the screening holes and fall through the funnel 4 to facilitate the subsequent classification and processing. At the same time, the larger volume of aged waste will fall directly through the discharge chute 23. The aged waste after screening is easy to process later and avoids the problem of fine solid waste becoming more fragmented.

A sliding rod 33 is fixedly connected to the top of the fixed plate 32, and a fixed block 34 is fixedly connected to the bottom end of the sliding rod 33. A sliding block 35 is slidably connected to the sliding rod 33 near its bottom end. A feeding trough 371 is fixedly connected to the right side of the sliding block 35. A feeding port 372 is opened on the left side of the feeding trough 371. A fixed frame 37 is fixedly connected to the rear side of the feeding trough 371. A worm gear 38 is rotatably connected to the right side of the fixed frame 37. A worm wheel 39 is rotatably connected to the left side of the worm gear 38 within the fixed frame 37. A second motor 36 is fixedly connected to the top of the fixed frame 37 corresponding to the worm gear 38. A rack 391 meshes with the left side of the worm wheel 39. The front side of the rack 391 is fixedly connected to the right side of the support frame 1.

[0034] With the feeding mechanism 3 in place, when the feeding trough 371 is at the bottom of the sliding rod 33, the baffle 31 can directly place the aged waste into the feeding trough 371. When the second motor 36 is working, the worm gear 39 and worm 38 work together to raise the worm gear 39 on the rack 391 and raise the feeding trough 371 to the top of the sliding rod 33. The baffle 31 does not block the feeding port 372 of the feeding trough 371, making it convenient for people to put the aged waste into the screening cylinder 28, which can make the screening and processing of the entire equipment more convenient in the later stage.

[0035] The second motor 36 is equipped with an output shaft, and the second motor 36 is fixedly connected to the worm gear 38 through the output shaft.

[0036] In actual operation, when this device is in use, the feeding mechanism 3 puts the aged waste into the screening bucket on the right side, and then drives the rotating rod 27 to rotate through the first motor 24 and the chain wheel group 25. At this time, the roller 26 will rotate along with it, driving the entire rotating drum frame 21 to rotate. At this time, the aged waste in the screening drum 28 with three different screening holes will be screened by centrifugal force, and the waste of different sizes will fall through the screening holes and fall through the funnel 4 to facilitate the subsequent classification and processing. At the same time, the larger volume of aged waste will fall directly through the discharge chute 23. The aged waste after screening is easy to process later and avoids the problem of fine solid waste becoming even more fragmented.

[0037] When the feeding trough 371 is at the bottom of the sliding rod 33, the baffle 31 can directly place the aged waste into the feeding trough 371. When the second motor 36 is working, the worm gear 39 and worm 38 work together to raise the worm gear 39 on the rack 391 and raise the feeding trough 371 to the top of the sliding rod 33. The baffle 31 does not block the feeding port 372 of the feeding trough 371, making it convenient for people to put the aged waste into the screening cylinder 28, which can make the screening and processing of the entire equipment more convenient in the later stage.
